RESUMO
BACKGROUND: Drug-induced panniculitis are uncommon. We report the second case of panniculitis induced by MINE chemotherapy. CASE REPORT: A 31-year-old woman with relapsed Hodgkin disease was treated with MINE cytostatic regimen. Multiple erythematous and painful nodules of panniculitis developed on her chest, abdomen and thighs fifteen days after the beginning of drug administration with a second flare up after second administration of the same drugs. The eruption cleared slowly after treatment withdrawal. DISCUSSION: To our knowledge, our case is the second reported case of panniculitis induced by MINE chemotherapy. Drug-induced panniculitis is uncommon and usually induced by steroid treatment. Some cases of panniculitis induced by atenolol, potassium bromide, apomorphine, interferon alpha and interleukin 2 have been described. Few cutaneous adverse effects are reported with MINE chemotherapy: rash, erythema and swelling of extremities. A case of inflammatory swelling of thighs with hemorrhagic panniculitis due to this treatment has been described recently.

BACKGROUND: Leprosy and vitiligo are common affections in the West Indies. Vitiligo frequently occurs in lepromatous patients, an observation rarely reported in the literature. METHODS: We studied the prevalence of vitiligo in patients affected by leprosy by performing a retrospective study between 1978 and 1999 in the French West Indies (Martinique). RESULTS: Eleven patients presented with vitiligo among 101 with lepromatous (multibacillary) leprosy. None presented with vitiligo among the 364 with the tuberculoid (paucibacillary) form. The mean age of the vitiligo patients was 55. 4 years at vitiligo onset. The sex ratio was 0.8. Vitiligo occurred 19 years after the diagnosis of leprosy, with a range from 3 to 42 years. The prevalence of vitiligo in lepromatous patients was 10.9%, compared to 0% in tuberculoid patients. Such an increase in prevalence compared with that in the general population (0.34%) was shown to be highly significant (P< 0.0001). CONCLUSIONS: Our data confirmed that the association of vitiligo and leprosy was not fortuitous. The physiopathology leading to this high rate of vitiligo in lepromatous leprosy is unclear, despite the fact that autoimmunity plays a major role in both diseases.

BACKGROUND: Mycetoma is a chronic subcutaneous tumefaction with presence of grains or granules. Etiological agents include bacteria or filamentous fungi. Mycetoma due to dermatophytes is uncommon, mainly occurring in Africa. To our knowledge, no case has been reported in the West Indies. Only two observations of Micosporum canis mycetoma in humans have been reported in the literature. We report a third case of mycetoma of the scalp caused by this fungus. CASE REPORT: A 22-year-old woman from Martinique, French West Indies, presented with an indolent tumefaction of the scalp evolving over five years. She had mental retardation due to congenital adrenal hyperplasia with 21-hydroxylase deficiency. The lesion was extracted surgically. Pathology and mycology examinations showed features of Microsporum canis mycetoma. Two months later, the scalp lesion recurred and the patient was treated with griseofulvin after surgical extraction. DISCUSSION: Mycetoma due to dermatophytes is very uncommon, mainly observed on the scalp and nape of the neck. A history of a skin lesion is frequent, leading to transcutaneous penetration of the fungus and mycetoma formation. Several dermatophyte species have been identified as causal agents (Microsporum ferrugineum, Trichophyton rubrum, Trichophyton verrucosum, Trichophyton mentagrophytes, Microsporum audouinii, Microsporum langeronii). Microsporum canis is rarely demonstrated in humans: two cases in children in Africa and Australia. Our observation was similar to the two cases in the literature: indolent and mobile tumefaction of the scalp, in a child or young adult, suggestive of lipoma or epidermal cyst, with excision leading to diagnosis. Association with tinea capitis and skin or nail involvement can also be observed.
